2 in 1 Dog Training Collar Automatic Anti Bark Control with Remote Rechargeable and Waterproof for 3 dogs

I got this for my Yorkie, who had a bad barking habit (would bark at nothing). After the first two times on “shock”, I turned it on to only vibrate and it’s enough to get her to stop immediately when it beeps. Holds a charge and has worked great. I just wish they made a smaller version, as Its pretty heavy/bulky for our tiny dog.
